“…It is noticed that if the value of h e is greater than zero, the entire MPDU will be retransmitted. According to (21) and Fig. 3, the recurrent function R j (D) at the jth state defined for the proposed AH-ARQ scheme to transmit A-MPDUs in one TXOP channel reservation can be reformulated as…”

“…On the other hand, type-III of H-ARQ scheme [20], considered as a partial IR scheme, not only decrements the coding rate but also maintains the selfdecoding capability in each retransmission. It is noted that the IR-based algorithms in general make use of either the rate compatible punctured convolutional (RCPC) codes [20,21] or the rate compatible punctured turbo (RCPT) codes [22]. Furthermore, the transmission errors are corrected in two phases based on the design concept of concatenate code [23].…”

Based on the IEEE 802.11n standard, frame aggregation is considered one of the major factors to improve system performance of wireless local area networks (WLANs) from the medium access control (MAC) perspective. In order to fulfill the requirements of high throughput performance, feasible design of automatic repeat request (ARQ) mechanisms becomes important for providing reliable data transmission. In this paper, two MAC-defined ARQ schemes are proposed to consider the effect of frame aggregation for the enhancement of network throughput. An aggregated selective repeat ARQ (ASR-ARQ) algorithm is proposed, which incorporates the conventional selective repeat ARQ scheme with the consideration of frame aggregation. On the other hand, the aggregated hybrid ARQ (AH-ARQ) protocol is proposed to further enhance throughput performance by adopting the Reed-Solomon block code as the forward error correction (FEC) scheme. Novel analytical models based on the signal flow graph are established in order to realize the retransmission behaviors of both schemes. Simulations are conducted to validate and compare the proposed ARQ mechanisms with existing schemes based on service time distribution. Numerical results show that the proposed AH-ARQ protocol outperforms the other retransmission schemes owing to its effective utilization of FEC mechanism.

“…One way to reduce the occupied bandwidth is by using punctured convolutional codes [3][4]. Punctured convolutional codes can also provide variable rate convolutional code, an important part of unequal error protection in wireless telecommunication systems [5][6]. A puncturing process deletes a number of bits in the codeword produced by a convolutional encoder [3].…”

“…It is shown that the RCPCencoded MIMO-OFDM system has better performance compared to the same system with only antenna diversity. However [6] does not cover a V-BLAST signal processing scheme to exploit multiplexing gain of the system. The mathematical expressions of BER for uncoded V-BLAST MIMO system with MMSE and ZF detections are given in [7].…”

We propose a Vertical Bell Laboratories Layered Space-Time (V-BLAST) MIMO complemented with RateCompatible Convolutional (RCPC) codes with Zero Forcing (ZF)and Minimum Mean Squared Error (MMSE)-based detection, as a way to attain high-capacity and highly reliable wireless system. The analytical BER of the system is presented and numerically analyzed. The system performance is analyzed in Nakagami-m fading channel, as it is adaptable to various signal statistics and covers a wide range of fading models. Equivalent convolutional code is used to mitigate the complexity arising in the calculations of the RCPC codes parameters. Results show that the use of highrate code allows for bandwidth efficiency while keeping the performance degradation at a minimum level not exceeding 1 dB. It is also shown that the proposed system is able to yield good performance even at the minimum number of antennas. Keywords-equivalent convolutional code, Nakagami-m fading, V-BLAST MIMO, RCPC
